If you’re working with an InfoPath form and are trying to display it as a web enabled form but are getting errors saying the form template failed to load, it may just be due to the manifest for the XSN not containing the relative URL base.<\/p>\n

For the following ULS errors:<\/p>\n

The form template failed to load. (User: …., Type: NullReferenceException, Exception Message: Object reference not set to an instance of an object.)<\/em>

The first version deployed worked perfectly but updates to the form were causing the errors shown at the start of this post.  Updating the template.xml file (contained within the xsn file) resolved the errors.<\/p>\n","protected":false},"excerpt":{"rendered":"
